What is general electronic configuration?

Electronic configuration or general electron configuration or electronic structure of atoms or ions is the arrangement of orbital energy levels for s, p, d, and f-block elements of the periodic table.

Which group are p-block elements in the periodic table write the general electronic configuration of a p-block element?

Groups 13, 14, 15, 16, and 17 elements comprise the p-block elements. The general configuration of p-block elements is ns2np(1−6).

What is the general configuration of p- block elments?

The general electronic configuration of p-block elements is ns2np1-6 (Except Helium). The number of electrons in the p-block element's penultimate shell is either 2 or 8 or 18.

Therefore, the element belongs to the p-block.

What oxidation state(s) can the alkaline earth metals exhibit?
iragen [17]

Answer:

+2

Explanation:

Alkaline earth metals are present in group 2 of periodic table. There are six elements in second group. Beryllium, magnesium, calcium, strontium, barium and radium.

All have two valance electrons.

Electronic configuration of Beryllium:

Be = [He] 2s²

Electronic configuration of magnesium.

Mg = [Ne] 3s²

Electronic configuration of calcium.

Ca = [Ar] 4s²

Electronic configuration of strontium.

Sr = [Kr] 5s²

Electronic configuration of barium.

Ba = [Xe] 6s²

Electronic configuration of radium.

Ra = [ Rn] 7s²

They are present in group two and have same number of valance electrons (two valance electrons) and show oxidation state +2 by loosing two valance electrons. They also show similar reactivity.

They react with oxygen and form oxide.

2Ba   +   O₂   →    2BaO

2Mg  +   O₂   →    2MgO

2Ca +   O₂   →    2CaO

this oxide form hydroxide when react with water,

BaO  + H₂O   →  Ba(OH)₂

MgO  + H₂O   →  Mg(OH)₂

CaO  + H₂O   →  Ca(OH)₂

With sulfur,

Mg + S   →  MgS

Ca + S   →  CaS

Ba + S   →  BaS

Complete the mechanism for the reaction by adding the missing curved arrows, atoms, bonds, charges, and nonbonding electron pair
Keith_Richards [23]

Answer:

See explanation below

Explanation:

In picture 1 attached, we have the starting structure. In picture 2, you have the answer for this.

Basically this is an acid base reaction to promove then, a condensation of the molecule.

In the first step, the carbonile substract a H atom from the HCl. Then, by resonance the OH+, pass the charge to the carbon, which is tertiary and can be easily stabilized. Now, after this, the Chlorine substract an Hydrogen to get a double bond on the carbon with the charge, and this be stable. Now, a second molecule of benzaldehyde reacts with this, so we can have a condensation product.

See picture 2 for complete mechanism.

Predict the electron pair geometry and the molecular structure of each of the following molecules or ions: (a) ClNO (N is the ce
S_A_V [24]

Answer:

See explanation

Explanation:

In ClNO , nitrogen is the central atom here. The central atom has a tetrahedral electron pair geometry and a lone pair on the nitrogen atom. Due to the lone pair, the electron pair geometry is now trigonal pyramidal.

The molecule CS2 has a linear molecular geometry. There are four electron groups around the central atom hence the electron pair geometry is tetrahedral but the molecular geometry results from the repulsion of the two double bonds.

The electron domain geometry for Cl2CO  is tetrahedral since there are four electron pairs around the central atom. However, the molecular geometry is trigonal planar due to the sp2 hybridization of the central carbon atom.

The electron domain geometry of Cl2SO  is tetrahedral due to the four electron pairs around the central atom. However, due to the lone pair on sulphur, the molecular geometry is  triagonal pyramidal.

In SO2F2, sulphur the central atom is surrounded by four electron pairs which are all bonding groups hence both the molecular geometry and the electron pair geometry is tetrahedral.

In XeO2F2, the central atom is Xe. There are five electron pairs around the Xe central atom four of which are bonding groups. The electron domain geometry and molecular geometry is trigonal bipyramidal.

For ClOF2 , the central atom Cl is surrounded by four electron pairs hence the electron pair geometry is tetrahedral but it is an AX3E(three bonding groups and one lone pair are present in the structure) specie hence it is trigonal pyramidal.
